The White House reportedly demanded "zero jailbreaks" for a Fable 5 relaunch, and security experts say that's impossible.

New reporting (June 17-18, via WIRED/Washington Post coverage) details the standoff behind the June 12 Claude Fable 5 / Mythos 5 suspension: SK Telecom's access was revoked, then an Amazon-filed vulnerability report triggered the global export ban. The administration, via David Sacks, reportedly gave Anthropic an ultimatum, eliminate all jailbreaks or de-deploy, and Dario Amodei refused both. Researchers say a zero-jailbreak guarantee isn't technically achievable, which matches everything in today's Security section. You can patch the vector, you can't prove the absence of all jailbreaks. Anthropic's Chris Ciauri says the models are "very confident" to return "within days," while a June 20 refund cutoff and June 22 free-trial close loom for affected subscribers. The policy is asking for a mathematical guarantee the field can't provide. That gap is going to matter well beyond this one suspension.
